HENRY A. BENNETT, OF NEW HAVEN, CONNECTICUT.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 346,142, dated July 27, 1886.

v Application filed May 13, 1886. Serial No. 202,110. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY A. BENNETT, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Sash Fasteners, of which the following is a specification, reference being had therein to the accompanying drawings, in which' Figure 1 is a plan view of the fastener. Fig. 2 is a plan view of the base-plate. Fig. 3 is a view of the upper side of the latch, and of the cams operating it, in broken lines; and Fig. 4. is a view of the under side of the latch. Fig. 5 is a view of the under side of the lever and cams, and Fig. 6 is a section on broken line in Fig. 1.

My invention belongs to that class of sashfasteners in which the latch is moved back and forth in the direction of its length, whereby the meeting-rails of the sashes are drawn together and the latch is locked.

The object of my invention is an improvement in the construction and operation of this class of fasteners. f

To this end the invention consists in novel parts and combinations, which are hereinafter more fully described and claimed.

The base-plate A, as shown in the figures, is of the kind known in the art as a raised plate, but it may be either a flat or raised plate, as preferred. It has the usual screwholes for fastening it to the sash by screws. Its central part, B, is raised, as shown in Fig. 2, and more distinctly in Fig. 6. I11 the edge of the round part the locking-slots a and b are made, and the raised and circular part between these slots is smaller than the remainder of the raised and circular partthat is, corresponds to an arc of a smaller circle. By this construction the pin in on the latch can move outside of the part c of the plate, and will strike against the sides of the slots a and b and limit the movement of the latch. The two locking slots (1 and e extend through the plate and open into the curved slot f, also extending through the plate. The pin a on the latch, moving in these slots, performs the same function and in the same way as the pin m, before mentioned. The latch is fastened by G and the enlarged end h.

moving it endwise into the locking-slots in these two ways, or by these two devices the latch is doubly locked or fastened. It is obvious that either or both of these ways may be used, as preferred. The latch D has the usual hook on its end, and its circular part corresponds in size with the circular part of the plate. It has the slot g, to allow endwise movement, and the countersink E, extending the greater part of the way through the latch. Into the countersink the projections or points m and or extend, on which the cams act to operate the latch. 011 its under side are the pins m and n. The lever F has the round part The pivot or bolt t is firmly fastened in the round part, turns in the base-plate, and holds the parts of the latch together by a nut on its lower end; or the lower end may be riveted over a washer, as shown. A spiral spring may be placed on the pivot between the washer and base-plate, if desired. The cams r, s, and w are fastened to the lover, or are made in one piece with it. The cam r is formed to act as the lever is turned on the point at and move the latch, or the pins on its under side,out of the lockingslots, and as soon as it has passed the point the cam s engages the point 12, turns the latch, and moves the pins into the locking-slots. \Vhen the movement of the lever is reversed, the cam r performs the same function as before, and the cam 00 turns the latch and moves the pinsinto the lockingslots. It will be noticed that the cams s and a" perform two functionsviz.,turn thelatch and move the pins on the sameinto thelocking-slots. If preferred, another cam or lever may be used to turn the latch. When the latch is in the position shown in Fig. 1, the cams are in the position shown by the broken lines in Fig. 3.

The plate or hasp H has no novelty and needs no description to be understood.

Having described my improved fastener and the way the latch is operated by the cams, what I claim as new, and desire to secure by Letters Patent, is- 7 1. The latch D,having the countersink E, points m and at, extending into the same, slot 9, and either of the pins m and n, as described. 2. The lever F, having the pivot a, turning in the base-plate A, and on its under side the, In testimony whereof I affix my signature in cams r, s, and m, as and for the purpose depresence of two witnesses.

scribed.

3. The lever F, having the pivot a, turning HENRY A. BENNETT. in the base-plate, and the cams 1-, s, and x, in combination with the latch D, having the \Vitnesses: countersink E, points m and 01, extending into GEORGE TERRY,

the same, and slot substantially as described. CHAS. L. JOY.
